目前,在大多数硅酸盐砖厂中,养护车的连接采用人工将U型钢筋插入于养护车的连接孔中,俗称金钩钓鱼。这种办法费工费肘,使用不便。下面介绍一种西德灰砂砖厂养护车自动挂钩装置,可供参考。如图1所示,由主钩11、踏板12与转轴13组成主钩装置。主钩11焊于转轴13的一端,踏板12则用螺栓固定于转轴的另一端。 At present, in most of the silicate brick factories, the connection of maintenance vehicles uses manual U-bars to be inserted into the connection holes of the vehicle, commonly known as gold hook fishing. This method is costly and elbow, and it is inconvenient to use. The following is a description of an automatic hooking device for the maintenance vehicle of the West German lime sand brick factory, for reference. As shown in FIG. 1, the main hook 11, the pedal 12, and the rotating shaft 13 constitute the main hook device. The main hook 11 is welded to one end of the shaft 13, and the pedal 12 is bolted to the other end of the shaft.
